Tigran Sargsian

Dr. Tigran Sargsian


Tigran is a Researcher at Russian-Armenian University and Institute of Chemical Physics after A.B. Nalbandyan. He defended his PhD in Physics of Semiconductors with thesis entitled “Investigation of the Properties of Vertically Coupled Cylindrical Quantum Dots for Quantum Computations”. Tigran is also a part-time lecturer at the Department of General Physics and Quantum Nanostructure. His research topics are mainly devoted to the investigation of the effect of external perturbations on the properties of quantum nanostructures. His main responsibilities in the group include but are not limited to the computational modeling and theoretical study of nanostructures.
